Template override Template overrides are a way of changing the way Joomla shows something without changing the basic or core Joomla system. A template override is a layout file that is placed in a special subfolder of the template. If found, it will replace the standard layout file for that template.This means that as Joomla is upgraded to new versions you will not have to repeat all the changes you made.
Search engine optimization (SEO) The process of optimizing your pages to give them high-ranking placement in the search results page of a search engine (SERP) - including Google, Bing, Yahoo and other search engines.
Split Menu A split menu is where different levels of a single menu are displayed in two or more locations on a single web page. For example, a common requirement is for a menu of top-level items to appear at the top of the page. When one of the items is clicked the user is taken to a page where a secondary menu, say on the left of the page, shows second-level items within the scope of the top-level item. The menus appear in separate locations on the page, but are related because one shows only top-level items while the other shows second-level items. This idea can be extended to include menus for third-level items and beyond. This can be implemented in Joomla using a single multi-level menu then creating more than one menu module each referring to a different level. Reference: http://docs.joomla.org/Glossary
